Dr. Alberto Vivoni obtained
his B.S. in chemistry from Inter American University of Puerto Rico in 1988
and a Ph.D. in physical chemistry from the City University of New York in
1995. He studied vibrational spectroscopy as a graduate student and since
has specialized in computational chemistry. His current research interests
are in the area of molecular modeling. Presently, he is working, in collaboration
with other research groups, in the interpretation of raman spectra of thiopurines
and in theoretical calculations of transitions states of hydrogen transfers
of iron II complexes of biomedical interest. He also directs a project from
the Department of Education that involves the use of molecular modeling in
the chemistry curriculum and in undergraduate research. His most recent publications
are:
